Abstract
A turbocharger having a variable geometry turbine intake incorporating a mobile cylindrical piston ( ) for varying the area of the induction nozzle in the turbine ( ). Blades ( ) mounted on the piston for controlling the flow in the nozzle penetrate through a slotted heat shield ( ) having a central opening wherein the rear disc of the turbine wheel is embedded to provide a smooth aerodynamic flow in the turbine vanes. A shield ( ) engaged between the heat screen and a central housing of the turbocharger prevents the gas from the rear disc cavity from recycling into the cavity housing the blades further enhancing the aerodynamic flow. An axial actuating device ( ) is secured for operating the piston via a shaft coupled by a cross ( ) to the piston and coupled to an actuating hub ( ) in the actuating device by quick connect unthreaded connection ( ).
